SORT_FLAG_CASE flag not working

I am trying to do a case insensitive sort on a 2 dimensional array.

PHP Code:


		
			
foreach ($rows as $key=>$row) {

    $names[$key]=$row['Name'];

}

array_multisort($rows,SORT_STRING|SORT_FLAG_CASE,$names);

This yields the same result (lower case after all upper case) with or without the case flag. Perhaps new eyes can see what I am missing. TIA.

What version of PHP are you using? SORT_FLAG_CASE only exists in 5.4+.

Ah! 5.3.3. Is there an alternative to upgrading?

I'm betting you are going to say 'uksort'.

Just make all of the values you put into $names lowercase or uppercase.

Also you have the order of the $names and $rows arguments reversed in the call to array_multisort.

If you can't change the data on the way into the array (like if it comes from a database call) then you can use array_walk
